The yield at 14% moisture content of the Nangdam variety had the grain yield of 29.12 kg/ha, which was not significantly different from those of Lebnok variety which gave the grain yield of 26.20 kg/ha. The grain per panicle was not significantly different among the varieties. The Nangdam and Lebnok varieties had the grain per panicle of 161.00 and 146.00 grain, respectively. Both varieties of upland rice had the highest number of empty grain of 48.00 and 33.00 grain per panicle, respectively (Fig. 2b), number of low perfect grain of 53.00 and 57.00 grain respectively,
number of high imperfect grain of 35.00 and 30.00 grain per panicle, respectively. percentage of high chalky grain of 17.50 and 15.20%, respectively and breaking grain of 0.75 and 2.50%, respectively, which were not significantly different among the varieties (Fig. 3a).
